Perhaps you should try some spelling variations:
"modified allocation optimization algorithmss" » "modified allocation optimization algorithms", "modified allocation optimisation algorithm", "modified allocation estimation algorithms", "modified allocation optimization algorithmsss", "modified allocation optimisation algorithmss", "modified allocation estimation algorithmss", "modified location optimization algorithmss"
"modified parameter optimization algorithm" » "modified parameter optimization algorithms", "modified parameter optimisation algorithm", "modified parameter estimation algorithm", "modified parameters optimization algorithm"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified allocation optimization algorithmss") OR ("modified parameter optimization algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified allocation optimization algorithmss\") OR (\"modified parameter optimization algorithm\"))".
• Removing quotes may allow a broader search: (( modified allocation optimization algorithmss ) OR ( modified parameter optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified allocation optimization algorithmss") OR ("modified parameter optimization algorithm"))*.
